Optical Coherence Tomography and Multifocal Electroretinography in Diabetic Macular Edema: A Neurovascular Relation With Vision

Abstract

Neural changes set in before the clinical changes related to vasculopathy manifest in diabetic patients. Neuroretinopathy in patients with DME affects all retinal layers symmetrically in early stages, but impacts the middle retinal layers severely in advanced disease form. BCVA correlates with electrophysiological changes till the time morphological features are visible when stronger correlation is seen with anatomical disruption.
